Cross-posting a bit from Random Comments, so please forgive my geek pride. I wrote a Python script that recorded voltage data on my RPi B+ from a photocell "observatory" that I set up in my kitchen window. Managed to catch the light level signal of the local partial eclipse with my cheapo 10-bit ADC despite high overcast. Partial eclipse started at 17:28 UTC, reached maximum at 18:47 UTC, and ended at 20:00 UTC, 64% maximum coverage.

Didn't get to actually see the eclipse as I was on the other side of the state inside a hospital with my mother (it was overcast there anyway) so I am very glad I set up this data logger before I left that morning. It is...something.

EDIT: My mother and I were watching eclipse coverage on the Weather Channel when the nurse came in. She saw what we were watching and said that a bunch of doctors were going on about it and were scheduling procedures around the eclipse. She said (with an air of disdain) that she didn't know what all the fuss was about. My mother never hurt a person in her life, but the look she gave to the nurse caused her to instantly see the error in her ways. I was very proud.

I pulled these photos off of my wife's cell phone. 10 seconds apart, they show the moon's shadow entering Teton Valley. In the bottom photo we still have a few seconds of sunlight remaining where we are.
